K YORK, CORPORATION OF 4VIRGIN IA RAZOR `Application Afiled Julie 19,

This invention relates to'safety razors. of the type which has a singlecombination of elements adapted not only for shaving but for stropping of the blade used thereby and is an improvement upon my Patent N o. 1,432,949, granted on Oct. 24, 1922.

lThe invention has for an object thereof the provision of a safety razor of simple construction adapted lcto u'se standard types of blades and which may alternatively be used for shaving or, without the addition of any parts, adapt itself for use with the strop to sharpen the blade used thereby.

In the more preferred embodiment, my invention' contemplates as an object thereof the provision of a safety razor adapted to use a double edged flexible blade in which i a 'bladeholding assembly is provided cooperating with a frame guard and hand holding portion to hold and Hex a blade `for shaving'purposes with varying degrees of shaving positions and which may, by simple adjustment, be converted-into a stropping device for the n blade without completel dismountingfof'the razor and its attached blade holding assembly. l'

The invention still further has forpan object thereof the provision of'a 'safety razor adapted to be usedv as av stropping device ,which includes `a blade holding assembly adapted to cooperate with a-frame and guard for flexing a blade arcuately to obtain vary- .ing degrees of shaving positions, which may alternatively be adjusted to receive a strop whereby the blade. assembly is so mounted relatively to the frame portion as to automatically position the blade for best stropping effects in its movement upon apstrop.

The invention still further has for an ob-y ject thereof the provision of a safety razorf including` a blade holding assembly normally Y adjustable for shaving as desired, including.

means of ready replacement of the blade and i which may, by simple adjustment, permit the blade to be stropped in situ without dis- -mounting or disconnecting any parts thereof or the blade assembly.

In its preferred embodiment, my invention has for an object thereofthe provision of a safety razor suitable as a stropping device vbly operating member is capable of converted into a blade stropping device.

1926. Serial No. 117,035.

for blades including a frame guard and handle portion adapted to cooperate with a blade holding assembly arranged to be mounted relatively to said framel and handle so that a strop maybe inserted between said blade assembly and frame and by movement along The invention still further has for anlobj ectxthereof the provision of a stropping safety razor -in which a blade holding assembly is arranged to serve the double purposev of a stropping Adevice'having particular 'futility with a double edged flexible blade so as to automatically position the assembly for stroppingalternately each of the cutting edges provided and which assembly may be readilyadjusted relativeto a frame, including a guard` forexing the blade into positions'best suited for shaving.

The invention still further contemplates, as an object thereof, the provision ofarsafety razor which includes means for affording ready access to a blade holding assembly for replacement of a 'shaving blade to the assembly, simultaneously serving as means to strop a blade in situ and curve the blade for shaving purposes against an arcuately curved frame member, the means to arcuately curve the blade simultaneously serving todaugment the locking action of the blade holding assembly to prevent accidental unlocking of My invention still furthery contemplates asA an object thereof the provision of a safety razor having a blade holding assembly pivot` 100 a blade seating andqa blade shaping member when used in association with the frame including the guard member.

In general,l my invention contemplates as an object thereof the provision of a safety razor which is adapted to be used with a double edged flexible razor blade which may be used for shaving purposes or for stropping in situ without substantially disconnecting any of the parts but simply by a tensioning operation of -the associated' members thereof.

For the attainment of these objects and such further Iobjects as may appear herein 'or be hereinafter pointed out, I make reference to the accompanying drawing forming a part hereof, in which l Figure 1 is a perspective view of my assembled safety razor;

Figure 2 is a partial section taken o n a line 22 of Figure 1 Figure 3 is a view similairto Figure 2 with parts adjustedout of the shaving position and ready for stropping;

Figure 4 is a section on ure 2;

Figure 5 is a section on a line 5 5 of Figure 3 with my deviee shown in connection with a strop;

Figure 6 is an end elevation of the rview slown in Figure 2 from the right end thereo v Figure 7 is a plan view of my device with the blade shaping member removed.

Referring to the drawings, my device has been illustrated as best adapted for use in connection with a double edged thin flexible blade and comprises a frame member 10, preferably arcuately contoured, having its oppositely disposed side edges formed as guards or combs 11 and 12. A11 annular member l,13, preferably hollow, is iXedly attached to the frame at its lower central portion by screw engagement upsetting or in any other desired manner and through the central portion thereof there is arranged a tensioning a line 4--4 of Fig- 1 member 14 disposed therethrough, having at its outer end a knurled knob 15 and at its up-` ,per end a screw engaging portion 16, for purposes which will be hereinafter described.

Mounted upon the frame 10 previously described, I provide a blade holdin assembly comprising a blade retaining mem er 17 and a blade shaping member 18 separably connected as by a hinged joint formed of lugs 19 and a pin 19 passing therethrough; rl `here is provided on the blade retaining member downwardly disposed extension members 20 and 21 having at their extremities pivot pins 22 and 23. l The extension members 20 and `21. and the pins carried thereby are arranged v l topass into the respective slots 25 in the l.

frame member 10, the sidewalls of the latter being formed with 'guide slots 26, 27 to lpermit relatively sliding movement of the pins 22 and 23 therein. The upper end walls 28 of the guide slots 26, 27' are preferably suitably formed to permit pivotal movement of the pins when abutting thereagainst.

As previously'described, the blade holdin assembly is composed of blade retaining member 17 and blade shaper member 1 8, and

vso

the member 17 is formed with blade positionof .the blade in a manner which .will be here` inafter described. l

lFor permitting ready accessA and replacement of the blade 30 between' the separable' parts 17 and 18, suitable means are provided and where I have connected the members 17 and 18by a hinged joint 19- and 19', the yoppositely disposed edge of 'the member 18 is provided with a latch member 31, hinged at 32 by the lugs and pin 33 and 34, respectively.

This latch is provided with a slot of contour approximating the ligure 8 and herein numbered 35. The latch 31 is made of a length sufficient to engage the pin 23, the latter member being formed upon its side walls with an annular groove 36 adapted to engage the slot 35 and belocked therewith, due tothe resilience of the side walls of the slotted latch 31 previously described.

As will be observed, the blade assembly may have relative sliding movement limited by the engagement of the pins 22 and 23 with the abutting walls 28 and when, moved to the limited posltion, as shown in Figure 3, may also have relative pivotal movement to the frame and handle member 10 and 13. In this position also, the latch member 31 may be released from the pin 23, as `shown in dotted lines in Figure 2, and more clearly shown in Figure 7, toA permit 'he replacement-of the blade member 30 between the blade assembly members 17 and 18.`

Where I use a double edged thin flexible blade,it is preferred to urge the blade against the frame member 10 to arcuately shape'the same in accordance with best shaving angles and for this purpose means are provided to urge the blade assembly against the arcuately shaped frame. There is therefore'provided on the blade retaining portion 17 va screw threaded portion 37 adapted to engage the screw threaded member 16. Engagement and 37 by turning of the of the portions 16 knurled knob 15 will serve to urge the-blade holding assembly upon the frame. The spaceY provided between the members of the assembly 17 and 18 will permit the sha er portion 18 to accomplish its intended ctionI of shaping the blade 30 in a well knownmanner. The effect produced is best illustrated in Figures 4 and 6, showing the limiting position of the blade assembly upon the frame curving the blade to its fullest extent. In this position also, the locking of the -blade assembly is augmented, due to tension'applied to the member 17, the`blade Shaper member 18 abutting against the frame 10 tending to exert tension upon the hinge 19 and the latch and pin connection 23 and 31.

Upon release of the screw connecting meinber 16, various angular displacements of the blade may be obtained and upon full release, as shown in Figures 3 and 5, ther blade will assume the fullest extension, permitting unhinging of the parts 17 and 18 for the replacement of the blade member 30 therebetween. In the 'position shown in Figure 3 where the blade assembly is latched and relatively located to be fully extended, a strop member 38 may be positioned therebetween as shown in Figure 5. In this position longitudinal movement along the length ofthe strop 38 will alternately present the edges of the blade 30 in stropping relation, either by .tilting of the handle`13 or, where I have arranged the blade assembly for pivotal movement-relative to the frame, the tilting action necessary for proper angular positioning of the blade is automatically accomplished as the device is moved back and forth along the` length of ,the strop 38, due to frictional engagement of separated from the assembly to change the lcoA razor to a stropping Adevice but in a simple manner and by using the simplest number ,of parts for providing a shaving device, I also provide a stropping device without any additional parts or unusual arrangement of the members relatively to each other. The assembly for holding the blade is further made proof against accidental separation of the blade from the separable bladev assembly by augmenting 'the lockin engagement against the latch 31 and the pm 23 when tension is sembly.

It will be further observed that for certain ,purposes the handle portion 13 may be a single structure by permitting the shoulder 13 ofthe handle 13 to 'have rotating action withintegral therewith. In this manner a single member may blade assembly tensioning device.v
